The objective of my research is to improve residue management
strategies (recycling principles) and guidelines for nutrient
conservation and soil carbon sequestration including effects on
competitive interactions between crop species according to temporal
nutrient demand and residue turnover. All activities are formulated
within the framework of climate change mitigation and sustainable
bioenergy production and typically in collaboration with companies
and other private investors. I have strong competences with work in
small-medium laboratory scale conditions as well as in larger
single field and farm systems. In this work comprehensive
experience with application of stable isotope techniques has been
obtained.
Ongoing activities includes: Recycling of single leftovers or
blends from biological (biogas and bioethanol) and thermal
conversion (gasification and pyrolysis) technologies to soil as
alternative phosphorous and potassium fertilizers and for soil
carbon sequestration; Design and test of cropping systems for
increasing production of biomass for bioenergy purposes and on the
same time safeguard soil fertility and food productivity;
Increasing the use of legumes for creating more sustainable
agroecosystems with the main focus on substituting nitrogen (N)
fertilization by symbiotic N2-fixation to mitigate
climate change |
